About our electronic leak detection in Thorpe Green
ELD finds breaches in the membrane, not every cause of water getting in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You will also know what to check next. Typical surveys look at patched roofs that still leak and leaks through a covered membrane, across commercial flat roofs, liquid-applied waterproofing and roof terraces and balconies.
In a village or hamlet like Thorpe Green, flat roofs are normally on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. If there are outbuildings or garages with flat roofs, mention them when you book.
We write the report in plain English, so you do not need to be a roofer to follow it. Photos show what each point refers to, and recommendations are put with the most urgent first where relevant.

Practical tips
Some practical points come up on survey after survey. They apply to most roofs:
- Share any drawings of the roof
- Check new waterproofing before handover
- Keep foot traffic on flat roofs to a minimum
- Clear flat roof outlets regularly
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Consider testing a new membrane before it’s covered. It is easier to find holes before more layers are added.

Your questions about electronic leak detection in Thorpe Green
Do you cover Thorpe Green?
We do. The survey and report are the same in Thorpe Green as anywhere else, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Thorpe Green?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is this a RICS survey?
No. We look at the roof, not the whole building, so it’s not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Can you find leaks on a covered flat roof?
In some cases. It depends on the build-up and the layers above the membrane, and some may need lifting. We talk this through first.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Let us know which days suit you as you book.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and the report notes anything we couldn’t see.
Do you need electronic leak detection in Thorpe Green?
Work on the roof can damage a membrane. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Look out for signs like these:
- Leaks that return after repairs
- Failed seams and laps
- Leaks under green or ballasted roofs
- New membranes needing a check before handover
If you look after a building such as Thorpe CofE Aided Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
What to check before booking
- Whether the roof space is looked at, where there is one
- Is there a chance to talk the report through?
- Are they insured for the work?
- How long the report takes to arrive
Electronic leak detection in Thorpe Green: local notes
In Surrey, older roofs are often handmade clay tile, with tile-hanging on many upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. With Botleys Mansion about 2.1 miles south, Thorpe Green sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
If yours is one of the older homes in the streets near Church of St Mary, flat-roofed rear additions and dormers added over the years are worth checking. If you own a rental within reach of Virginia Water station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

What we look for on each type of roof
Bituminous membranes
Many flat roofs use bitumen-based membranes. The build-up decides which method will work.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We look at this first.
How the survey works
On the day, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can be seen safely. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Thorpe Green, a postcode doesn’t always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before we arrive
- Dig out any old roof reports or invoices
- Make sure pets are kept safely away
- Make a note of anything you’d like us to look at
